Which robotaxi is most deployed?

Verdict: Waymo runs the largest deployed robotaxi service in the world

As of August 2026, Waymo operates roughly 4,000 driverless vehicles across about 15 US metro areas and is booking on the order of 500,000 paid rides per week, a figure the company disclosed publicly in March 2026 and has been reiterating through mid-year. No other operator matches that combination of geographic breadth (multiple US regions, freeways, 24/7 operation) and per-week ride throughput. Baidu Apollo is the credible counter-claim: Apollo Go crossed 300,000 weekly rides in early 2026, has service in more cities (about 20 in China plus expansions into Abu Dhabi, Dubai, and the Seoul metro), and its Wuhan operation is the single densest robotaxi city in the world at over 1,000 vehicles running fully driverless 24/7. If the question is "which brand is deployed in the most cities," Apollo Go wins. If the question is "which service is doing the most paid, fully driverless rides on public roads at commercial scale," Waymo wins, and it wins by a wide margin.

The rest of the field, Pony AI, WeRide, and Zoox, are meaningfully smaller in fleet and ride volume, though Pony and WeRide are on public growth trajectories that could re-order the middle of this list by year end.

The star: Waymo

Waymo confirmed 500,000 paid rides per week in a March 2026 TechCrunch disclosure, and repeated the number through July 2026 announcements that added four more US metros to fully driverless commercial service. Public cities as of mid-2026 with fully driverless commercial operation include Phoenix, San Francisco Bay Area, Los Angeles, Austin, Atlanta, Miami, and Nashville, with a July 8, 2026 announcement adding four more and a stated goal of 1 million weekly rides before end of year.

Independent trackers put the operating fleet near 4,000 vehicles across roughly 15 metros counted (some are early access or pre-launch; the seven above are full commercial service).

The service runs the Jaguar I-PACE today, with the sixth-generation Zeekr-based Waymo platform staged for the next fleet expansion. Freeway operation went live in the Bay Area in 2026, closing the last "highway gap" that had let critics say Waymo was a surface-street-only service. Cumulative paid rides since launch is now in the tens of millions.

Two things separate Waymo from every other operator on this list, and both are load-bearing for the "most deployed" claim:

1. Every ride is paid, driverless, and on public roads. There is no safety operator behind the wheel in commercial service. That is not universally true of the Chinese operators, whose "fully driverless" claim often applies to a subset of a fleet that still runs safety operators elsewhere.
2. The ride count is repeatedly disclosed against a real revenue line. Alphabet's Other Bets segment carries Waymo's revenue, so the 500,000 weekly rides number is anchored to filings, not marketing.

Runners-up, ranked

1. Baidu Apollo Go — the largest by city footprint, the densest by single-city deployment. Baidu disclosed Apollo Go hit 300,000 weekly rides in late February 2026 (CnEVPost), operates in around 20 Chinese cities as of January 2026, and expanded to 27 cities globally by May 2026 including Abu Dhabi (Yas Island, with K2's AutoGo), Dubai, and the Seoul metro. Cumulative orders passed 17 million in late 2025 and exceeded 22 million by April 2026. Wuhan alone runs 1,000+ Apollo RT6 vehicles fully driverless 24/7, the single largest one-city robotaxi deployment in the world; that deployment is also notable as the site of the first publicly documented fleet-wide system failure in a commercial robotaxi service, in March 2026. If the metric were "cities served," Apollo Go would be the winner. On paid rides per week, it is roughly 60 percent of Waymo's figure.

2. Pony AI — fastest-growing mid-sized operator. Pony reported passing 1,700 robotaxis by mid-2026 and, in May 2026, raised its year-end fleet target to 3,500 vehicles across more than 20 cities (Bloomberg). The company operates the Pony Gen-7 Robotaxi platform commercially in Beijing, Guangzhou, Shenzhen, and Shanghai, and is expanding into the Middle East and Europe via OEM partners. Ride throughput is not disclosed at the weekly cadence Waymo and Baidu use, but the fleet size alone puts Pony third today and potentially second by year end if the 3,500 goal is hit before Apollo Go's fleet grows commensurately.

3. WeRide — global-footprint play, smaller fleet. WeRide has publicly targeted 2,600 robotaxis globally by end of 2026 and runs the Robotaxi GXR commercially in Guangzhou and Beijing, plus international deployments (Abu Dhabi, and pilots via Uber in additional markets). WeRide's differentiator is being the operator most willing to run cross-border pilots at commercial cadence; the fleet remains meaningfully smaller than Apollo Go's or Pony's today.

4. Zoox — commercial launch, tiny fleet, purpose-built vehicle. Zoox opened its purpose-built (no steering wheel, no pedals, bidirectional) Zoox Robotaxi to paying public riders in Las Vegas in mid-2025 and expanded to San Francisco in 2026. Zoox is important because it is the only Western operator running a purpose-built vehicle in commercial service rather than a retrofitted OEM platform, but on the raw "most deployed" question it is at the far bottom of this list: the fleet is under a hundred vehicles, and the company reports "nearly two million autonomous miles" cumulative, which puts a Zoox week at a rounding-error fraction of what Waymo does in a day.

5. Others worth naming, well behind. Didi Robotaxi runs Chinese pilots but is not at commercial fleet scale. Motional has scaled back after Hyundai-Aptiv restructuring. Avride is running Hyundai Ioniq 5 pilots via Uber in a handful of US cities. Momenta and XPeng are further from commercial revenue. AutoX, which once looked like a leading contender, is now discontinued.

What "beats" Waymo, and why it doesn't count

Three claims routinely surface as challengers to Waymo's "most deployed" title. Each falls apart under a specific definition.

Tesla Robotaxi. Tesla launched a small robotaxi service in Austin in mid-2025 with safety monitors, then expanded to additional cities through 2026. The service is meaningful as a public disclosure but is orders of magnitude below Waymo on paid-ride throughput, still carries in-vehicle personnel in most markets, and the "fully driverless" claim has not been substantiated at Waymo's cadence of independent reporting. Tesla wins press cycles; on rides per week, it is not the answer.

Apollo Go's city count. As noted above, if the metric is number of distinct cities with commercial or pilot service, Baidu wins. The angle of this page (fleet size plus paid-ride throughput) makes Waymo the answer, but a reader looking specifically for "widest geographic footprint" should be pointed at Apollo Go.

Pony's year-end target of 3,500 vehicles. A target is not a deployment. Pony has stated the 3,500 figure publicly (Bloomberg, May 2026), but the currently reported number, as of Q2 2026, is above 1,700. Targets belong in a forecast, not in an answer about what is deployed today.

Gotchas and caveats

"Fully driverless" is not one thing. The Chinese operators disclose "fully driverless" as a fleet category that coexists with safety-operator vehicles in the same brand. Apollo Go's Wuhan deployment is genuinely 24/7 fully driverless at 1,000+ vehicles. Elsewhere the mix varies. Waymo, by contrast, runs zero safety operators in commercial service across every market it opens. Comparing "fleet size" without normalizing for this makes Chinese operators look larger than they are on the specific metric of driverless rides.

Weekly rides is a better metric than fleet size. A robotaxi that sits in a depot is not a deployment in the sense a rider cares about. Waymo has both the larger fleet and the higher published rides-per-week; if only one number were available, weekly rides is the tighter proxy for real deployment.

Ride revenue and unit economics are not the same as ride count. None of the operators on this list are cash-flow positive at the corporate level on the robotaxi line alone. Baidu has publicly targeted Apollo Go profit in 2026; Waymo remains inside Alphabet's Other Bets, which reported multi-billion-dollar operating losses. "Most deployed" says nothing about "most profitable."

Wuhan is the single most impressive city deployment, and Waymo does not operate there. Any answer to "most deployed" that fails to name the Apollo Go Wuhan marquee is incomplete: 1,000+ vehicles, one city, 24/7 driverless. The Waymo San Francisco deployment is the Western analog at roughly 800 Bay Area vehicles across the multi-year build-out.

The comparison changes if you count "cities announced" vs "cities open to the public." Waymo has publicly named more than a dozen additional cities coming in 2026 including Dallas, Denver, Houston, Las Vegas, Orlando, Washington D.C., and London. On the "open to paying public" metric, Waymo is at 7 US metros; on the "announced or in preview" metric, it is closer to 15. Apollo Go's 20+ Chinese cities include a mix of both.

Purpose-built vehicles are the next axis of competition. Waymo and Apollo Go both still run vehicles derived from OEM platforms (Jaguar I-PACE, Zeekr, retrofitted Chinese OEMs). Zoox is the only Western operator with a bespoke bidirectional pod in commercial service. That does not move the "most deployed" answer today, but on any 2027-and-later version of this question, purpose-built cost curves are likely to matter.

Bottom line

The answer to "which robotaxi is most deployed" in August 2026 is Waymo, on the strength of ~4,000 vehicles across ~15 metros and ~500,000 paid, fully driverless rides per week (a number Alphabet has reiterated publicly since March 2026). Baidu Apollo Go is the closest challenger, ahead on city count and holding the largest single-city deployment in the world (Wuhan, 1,000+ vehicles), but roughly 60 percent of Waymo's weekly ride throughput at ~300,000.

Pony AI and WeRide are the credible mid-sized operators with public growth targets that could shift the middle of this list by end of year. Zoox is the notable Western entrant, but at commercial-launch scale, not deployed scale.
